超声成像在结节性甲状腺肿并发腺瘤中的应用评价

Evaluation of Ultrasonography in Nodular Goiter with Thyroid Adenoma

目的 评价超声在结节性甲状腺肿并发腺瘤中的诊断价值 ,提高对甲状腺疾病多源性的认识。方法 对 4 0例甲状腺中的结节逐一进行仔细观察 ,评价二维图像和彩色多普勒血流图 (CDFI)的表现。结果 4 0例甲状腺病变共检出 15 7个结节 ,其中腺瘤结节 4 2个 ,结节性甲状腺肿结节 115个。实质性及囊实性腺瘤结节表现为包膜完整 ,周边有晕环并有环状包绕的血流信号。实质性及囊实性结节性甲状腺肿的结节表现为无包膜或包膜不完整 ,周边无血流或有短杆状血流显示。囊性腺瘤与囊性结节性甲状腺肿的鉴别诊断主要依据二维图像。结论 超声对提高甲状腺疾病多源性的认识 ,提高超声正确诊断率有重要的意义。

Objective To evaluate the diagnostic value of ultrasound in nodular goiter(NG)with thyroid adenoma(TA),so as to improve the discernment of ultrasonography of polyphyletic thyroid diseases.Methods Every nodule in 40 cases was evaluated on 2 DE and color Doppler flow images.Results A total of 157 nodules were detected,including 42 nodules of TA and 115 nodules of NG.Solid and mixed TA usually had complete capsules and perinodular circular blood flow;solid and mixed NG usually had no or incomplete capsules,no perinodular blood flow or only short bar blood flow.Differential diagnoses between cystic NG and cystic TA mainly depended on 2 DE display.Conclusions It is of clinical significance to improve the ultrasonographic discernment of the polyphyletic thyroid diseases so as to raise its ultrasonic diagnostic accuracy rate.
